At my (very small) college there was an email system where you could send emails to the entire campus. It pretty quickly turned into something that felt very similar to an online forum. It was conventional to use N/T at the end of subject lines for "No Text" when the subject line was all you needed to convey your message. Email was checked with enough frequency that it was commonly used for what we use SMS / text-messaging for today. You didn't really expect people to be near their landline phone, but you could connect with most students on campus pretty easily/rapidly with the e-mail system. This is an era before there was cell-phone service on campus, but cell phones were still very rare anyway.
